What is the temperature range of nitrile rubber

The use temperature range is relatively wide, and can usually be used in the following temperature ranges:

First, the conventional use of temperature range

Minimum temperature: about -30 ° C to -40 ° C (different sources vary slightly, but it is generally believed that it can remain elastic at lower temperatures)

Maximum temperature: about 100 ℃ nei 120 ℃ (long-term use temperature usually does not exceed this range)

Nitrile rubber seal ring can maintain good elasticity and sealing performance in the temperature range of -30 ℃ (or -40 ℃ ) to 120 ℃

2. Special conditions of use

In some special cases, the use temperature of nitrile rubber seals may exceed the above conventional range, but this usually needs to be determined according to the specific application scenario and material formulation.

At high temperatures, nitrile rubber may undergo chemical changes such as oxidation and hydrolysis, resulting in decreased performance. Therefore, if you need to use under high temperature conditions, you should consider choosing materials with better high temperature resistance, such as fluorine rubber or silicone rubber.

Third, use precautions

When installing and using nitrile rubber sealing rings, avoid improper operations such as excessive compression, distortion or bending to avoid affecting their service life and sealing performance.

According to the specific application environment and temperature requirements, choose the appropriate nitrile rubber sealing ring model and specification.

Nitrile rubber seals perform well in the temperature range from -30 ° C (or -40 ° C) to 120 ° C and are suitable for sealing needs in many fields. However, in high temperature environments, its performance may gradually decline, so it is necessary to choose the appropriate material and installation method according to the specific situation.
